Thanks so much for the watch! 

Ahh, a digital artist. I am not sure if my comments will be any help since I am a traditional artist and I don't know much about digital art but I will try to do my best.

Overall, your pictures are not too scruffy. You have quiet a nice cartoon style of drawing animals (well dogs, wolves and cats, anyhow).
The imediate problem I see are the watermarks, they are quiet distracting. I understand you don't want nobody stealing your art but a better way to go about such things is to include a signature in the corner of your drawings. Besides there are so many people here it is not very probable someone will steal your art and if you include a signature, people will be able to identify the art thief.
Another problem is the shading. The way you do coloring is quiet good. Nice and lush, perhaps a little bit too lush. In some of your drawings you draw darker furs and there usually merge with the lineart and make the whole charater a bit obscure, you know. It looks like a a black shape of a dog without any details because they are obscured.
There also does not seem to be much shading or lighting in your pictures. It is usually just one shade without many fur details or lighter shades to give the model sort of a 3D feel. You know, when one side of a character is darker and the other one is brighter.
I am sure you could be able to find some tools to made add some reflections to the eyes and some details to the fur. Details is what makes the drawing.

In terms of anatomy, your pictures look very good, all the animals are quiet well drawn in that regard, the only thing I would improve is the shading.
